Prophait builds integrated master schedules in your browser — a modern-day CPM engine, a spreadsheet-grade grid, and Claude built in as an assistant that speaks fluent scheduler.
Why Prophait
Project trackers can't compute a critical path. Legacy desktop tools can't share a link. Prophait does both jobs — without compromise on either.
"Add a 5-day design task after SRR and show me the critical path." The assistant reads and edits your schedule with real operations — every change undoable and audited.
CPM — the critical path method — is the math that makes a schedule defensible. Prophait runs the full forward and backward pass on every edit: links with lag, constraints, calendars, and float, with the critical path lit up in red across the grid and Gantt — and an inspector for programs that have more than one.
DCMA 14-point health checks, earned value (CPI/SPI) live on every schedule, named baseline archive, and an audit trail of every schedule edit. Program-review-ready without exporting a thing.
Claude, built in
Prophait's assistant is powered by Claude, Anthropic's frontier model — and it works with the same operations you do: adding tasks, linking logic, running analysis. Nothing it does is a black box, and every change is undoable. AI requests go directly to Anthropic on your own API key. Under Anthropic's current Commercial Terms, API data isn't used for model training, and Prophait never uses your schedules or chats to train any model.
Everything a planner expects
Keyboard-first grid: type to edit, arrow keys, copy and paste straight to Microsoft Excel, filter any column, freeze panes, group by slack or resource. Virtualized grid and Gantt, tested on 2,000-task schedules.
Import MS Project (.mpp and .xml) and Primavera P6 XER schedules with their outline, logic, constraints, calendars, resources and costs, progress and baselines. The import report names anything that doesn't come across, such as part-day durations and some resource calendars.
Every company is a separate tenant enforced at the database layer, not just the app. Invite-only team joining, checkout discipline against conflicting edits, and every schedule change audited.
Bring your own Anthropic API key. Anthropic bills your account directly at its own rates, and Prophait adds no AI surcharge. Your key is stored encrypted and never shown again in full. Assistant conversations are saved with the project, so your team can pick up the thread.
Capture named baselines before every review, compare live dates against the frozen plan, and re-apply an archived baseline when the replan gets walked back.
See per-day demand against capacity on a histogram under the Gantt, and resolve over-allocation with one click of delay-based leveling — pinned tasks respected.
Create Jira issues straight from tasks, push names, notes, and due dates, and pull status back into % complete — deterministic, on-demand sync with org credentials stored encrypted.
Every workspace ships with a full CubeSat development program and a MIL-STD-881-style WBS — copy one and start planning instead of staring at an empty grid.
Hand customers and reviewers a live, read-only view of the schedule — no account, no export. Links expire after seven days and can be revoked the moment a review ends.
Pricing
Every plan includes your first editor free. Upgrade when your team grows — you pay only for each additional person who edits schedules.

Free
per company
1 free editor; viewers free. Full CPM, EVM, and DCMA checks, MS Project and P6 import, and the AI assistant with your own key.
$29
per additional editor / month, billed monthly, plus applicable tax
Your first editor stays free, and each additional editor is $29 a month: two editors cost $29 a month, three cost $58. Viewers and stakeholders are free. Everything in Starter, plus the two-way Jira integration.

Contact us
priced by contract
On-premises deployment inside your own environment, so controlled data stays within your own security and export-control boundary. Enterprise SSO, security review support, and an SLA.
Security
Schedule data is competitive data, and Prophait treats it that way at every layer. The shared service is for unclassified, non-controlled data only — do not upload CUI or ITAR/EAR-controlled technical data.
Every company is a separate tenant enforced with Postgres row-level security — a second, independent wall beneath the application layer.
API keys and integration tokens are stored encrypted and write-only — even admins only ever see a masked hint.
Task edits, AI actions, membership changes, baseline captures — who, what, and when, in an append-only trail at the database layer.
TLS on every connection to Prophait, role-based permissions, invite-only team joining, and checkout discipline so two planners never trample one schedule.
